(Undated) — Northern California is finally seeing a shift in the weather, moving from cooling to clouds and rain, followed by strong winds and fire risk. Wind gusts could reach up to 35 miles-per-hour in the Valley and 60 miles-per-hour in the Sierra.

Dry vegetation and gusty winds create critical fire conditions, with potential Public Safety Power Shutoffs affecting up to 30 counties.

PG&E has issued warnings for possible power outages. Winds are expected to ease by Saturday night, with calmer, sunny weather by Sunday.
